Pretty cool. I went all out like that a few years back, and a friend talked me into the case with the size window, and the cold cathode lights. I went UV on the 12" tubes and found some fans with UV lights, and I painted the inside with UV paint, etc. Problem was I have this thing in my bedroom, and it is so dang bright that I can't leave it on and get any sleep.
So for about 2 years now, I've left the cold cathodes off, and replaced all but 1 fan to ones without lights. Now it glows still, but not as bright. Still bright enough to be annoying though.
So, don't put it in your bedroom unless you like sleeping with a bright light on.
